RAILWAY-GATE.

1 SPECIFICATION forming part of Letters Patent No. 598,605, dated February 8, 1898.

Appfication filed June 18,1896. Serial No. 595,969. [No model.)

To all whom it may concern:

Be it known that I, J AMES W. PARSONS, a citizen of the United States, residing at Wilmington, in the county of New Castle and State of Delaware, have invented certain new .ful improvements in gates for railroad-crossings,the object of the same being to provide two pairs of gates,one pair on each side of the railroad-tracks, the members of each pair being adapted to operate at the same time and both pairs being adapted to be operated from the same side of the track.

The invention consists of a pair of. gates pivot-ally mounted in suitable uprights on one side of the track, T-levers f ulcrumed in brackets located within each upright, a drum upon the pivotalshaft upon which each gate is mounted, cords connecting two ofthe arms of each of said T-levers with said drum, a pitman connecting the remaining arms of said levers together, a similar pair of gates similarly mounted on the opposite side of the track, a supplemental drum on the shaft upon which one of said gates is mounted, a supplemental T-lever fulcrumed in a bracket beneath said drum, cords connecting the two arms of said T-lever and said drum, and suitable connections between the other arm of said lever andone arm of one of the levers attached to one of the gates on the opposite side of the track. l v

The inventionalso consists in other details of construction and combinations of parts which will be hereinafter more fully described and claimed.

In the drawings forming part of this specification, Figure 1 represents a plan view of my gates in their closed position, showing the railway-tracks between them. Fig. 2 is a side elevation of the gates on one side of the crossing, showing the same in their closed position. Fig. 3 is a similar View of the gates on the opposite side of the track, showing them in raised position. Fig. 4 is a vertical section through the shaft upon which one of the gates is mounted, showing the two drums thereon. Fig. 5 is a similar view taken at right angles thereto between the drums.

Like reference-numerals indicate like parts in the different views.

' A pair of gates 1 2 on one side of the track are pivotally mounted in uprights 3 and 4, and within each of said uprights, mounted in suitable brackets 5 5, are T-levers three arms 8 9 10 thereon. The arms 8 9 have attached to them cords or chains 11, which pass around and are secured to drums 12 12, secured to the shaft 13, upon which the gates 1 and 2 are mounted. The remaining arms 10 10 of the T-levers 6 '7 are connected through a pitman 14, as clearly shown. The cord 11, attached to the drum 12 of the gate 2, passes directly around said drum, but the cord 11, attached to the drum 12 of the gate 1, is crossed upon itself, as clearly shown in the drawings. By this construction it will be evident that by rocking one or the other of the T-levers 6 or 7 both of the gates l 2 will be raised or lowered simultaneously.

Leading from the arm 10 of the T-lever 6 is a pitman 15, which is pivoted to a bellcrank lever 16, fulcrumed upon a block near the surface of the ground, and the other arm of said bell-crank lever has connected to it a second pitman 17, which is pivoted'toa similar bell-crank lever 18 on the opposite side of the track. The gates 19 and 20 on the opposite side of the track are mounted similarin all respects to the gates 1 and 2. Within the uprights21, however, upon which the gate 19 is pivoted,

is mounted in a bracket 22 a supplemental QT-lever 23, one arm of which is connected through a pitman 24 with the other arm of the bell-crank lever 18.

the lever 23 have connected to them the cord 25, which is connected to the periphery of a drum 26, loosely mounted upon the shaft 27, to which the gate'19 is secured. This drum 26 has secured to one side thereof a segmental rack 28, with which meshes a pinion 29 upon the inner end of a shaft 30, extending out through the sides of the upright 21. The said shaft has an operating lever or crank 32 upon its outer end, by means of which it may be turned. The drum 33, which is secured to the shaft 27, upon which the gate 19 is mounted, is provided with a similar rack 34:, with The other arms of 6 7, having which meshes a pinion 35 upon the inner end of an operating-shaft 36, having a crank 37 upon its outer end.

From the foregoing description it will be evident that the gates 19 and 20 may be raised or lowered simultaneously by turning the shaft 36, and that the gates 1 and 2 on the opposite side of the track may be raised or lowered simultaneously by turning the shaft through the crank 37 upon its outer end. When this is done, the pinion 29, meshing with the segmental rack 28, turns the looselymounted drum 26, and through the cord 25, connected to said drum, rocks the T-lever 23 in its bearings. This through the pitman-24,

bell-crank lever 18, pitman 17 bell-crank lever 16, and pitman 15 rocks the T-levers 6 7, connected to the gates l and 2 on the opposite side of the track, and raises or lowers said gates according to the direction in which the shaft 30 is turned.

Having now described my invention, wha I claim as new, and desire to secure by Letters Patent, is

1. The combination of a pair of gates mounted to rock in suitable uprights, drums secured to the shafts upon which the gates are mounted, T-levers mounted in brackets within each upright, a cord attached to two arms of each of said levers and secured to the edge of one of said drums, a pitman connecting the remainin g arms of said T-levers and means for rocking said T-levers in their bearings, whereby said gates may be opened or closed simultaneously.

2. The combination of a pair of gates mounted to rockin'suitable uprights, drums secured to the shafts upon which the gates are mounted, a segmental rack upon the edge of one of said drums, an operating-shaft mounted in said uprights, a pinion on said shaft meshing with said rack, T-levers mounted in brackets within each upright, a cord attached to two arms of each of said levers and secured to the edge of one of said drums and a pitman connecting the remaining arms of said T-leve rs, substantially as and for the purpose described.

3. The combination with two pairs of gates mounted to rock in suitable uprights on opposite sides of a railroadtrack, drums secured to the shafts upon which said gates are mounted, a T-lever mounted in brackets adjacent to each of said drums, a cord connecting two of the arms of each of said T-levers with the edge of the drum nearest thereto, pitmen connecting the remaining arms of the T-levers attached to the respective members of the two pairs of gates, two bell-crank levers on opposite sides of the track, a pitman connecting together one arm of each of said bell-crank levers, a pitman connecting the other arm of one of said bell-crank levers with one arm of the T-lever connected to the gate adjacent thereto, a supplemental drum loosely connected to the shaft upon which the opposite gate is mounted, a supplemental T-lever mounted in a bracket adjacent to said supplemental drum, a cord connecting two of the arms of said lever with the edge of said supplemental drum and a pi tman connecting the remaining arm of said T-lever with the other tially as and for the purpose described.

4. The combination with two pairs of gates mounted to rock in suitable uprights on opposite sides of a railroad-track, drums secured to the shafts upon which said gates are mounted, a T-lever mounted in brackets adjacent to each of said drums, a cord connecting two of the arms of each of said T-levers with the edge of the drum nearest thereto, pitmen connecting the remaining arms of the T-levers attached to the respective members of each pair of gates, two bell-crank levers on opposite sides of the track, a pitman connecting together one arm of each of said bell-crank levers, a pitman connecting the other arm of one of said bell-crank levers with one arm of the T-lever connected to the gate adjacent thereto, a supplemental drum loosely connected to the shaft upon which the opposite gate is mounted, a supplemental T -lever mounted in a bracket adjacent to said supplemental drum, a cord connecting two of the arms of said lever with the edge of said supplemental drum, a pitman connecting the remaining arm of said T-lever with the other arm of the otherbell-crank lever, a segmental rack upon said supplemental dru m, a pinion meshing with said rack and an operating-shaft to which said pinion is connected,

arm of the other bell-crank lever, substansubstantially as and for the purpose described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
